TVS (Transient Voltage Suppressor) varistors, MOVs (Metal Oxide Varistors) and Diodes are commonly used in the modern industry for protection of sensitive electronic devices. ROV20H151K-2 is a high voltage Surge Varistor, and is one of the high performance Transient Voltage Suppressors from ROHM Semiconductor’s product family. It is widely used as an ideal choice for surge protection due to its high peak pulse current, low capacitance and a wide range of operating temperature range.

ROV20H151K-2 is a two-terminal metal-oxide varistor designed for use in highly reliable and commercial applications. It is rated to a maximum voltage of 1500V with a maximum peak pulse current of 20A. The device also features an anti-static protection design, which limits any electrostatic discharge (ESD) damage to the device from the environment. It also has been designed to provide superior reliability even in high temperature applications and hence can be used in various automotive, industrial and consumer equipments.

The working principle of the ROV20H151K-2 varistor is based on the principle of a diode junction. It is constructed with two layers on which a junction is formed. When a voltage is applied to the device, it will cause a flow of current. This current is then divided into two parts, one flowing through the junction and the other one going through the reverse direction. This process generates a change in the voltage, which is proportional to the current. The current flowing in the junction will depend on the resistance of the junction and the voltage being applied. However, if the voltage becomes too high or if there is a sudden rise in the voltage, the varistor will be able to dissipate the surge current, thus protecting the device and its surroundings from further damage.

The ROV20H151K-2 varistor can be used in many different applications in a variety of areas including computers, automotive, consumer electronics, telecom, power supplies, solar cells and others. It is used to provide protection against transients, surges, and high voltages. The device’s characteristics make it an ideal choice for power line protection, where its excellent performance characteristics are key. It can also be used in conjunction with other devices, such as diodes and MOVs, for even better surge protection. The device is also useful in distributed power supply systems, where it can be used to protect the system from power surges, voltage transients, overvoltage and overcurrent.

In conclusion, the ROV20H151K-2 is a high-performance, two-terminal, metal-oxide varistor which offers superior and reliable surge protection for various applications such as computers, automotive, consumer electronics, telecom, solar cells and others. The device features an anti-static protection design, high peak pulse current, low capacitance and a wide operating temperature range. This makes it an effective solution for protecting devices from voltage transients, surges, and other voltage anomalies.
